Analysis

Chosun Refractories Co (462520) currently trades at 13,800 KRW, while our model-based Fair Value estimate is 5,224 KRW, implying the stock looks roughly 62.2% overvalued today. The Quality Score stands at 53/100 (solid quality), in the Basic Materials sector. Bear case: priced above our estimate, the market already discounts strong expectations. Bull case: above-average quality can justify a premium, the entry price still matters most (evidence: medium).

Over the trailing twelve months, Chosun Refractories Co generated revenue of 533B KRW at a net margin of 1.2%. Revenue grew 0.8% year over year. It earns a return on equity of 3.0%. Net debt stands at 160B KRW. Fundamentals as of Jul 22, 2026

Our scenario range runs from 3,657 KRW (bear case) to 6,791 KRW (bull case); at 13,800 KRW, the current price sits above that range. Bear and bull are the same models run on conservative and optimistic assumptions (margins, growth, valuation multiples), so a plausible valuation range, not a price target. The share trades about 26% below its 52-week high and 12% above its 52-week low, currently below its 200-day average. For context, the median of 10 Basic Materials peers we cover trades at -59% fair-value upside, at -62%, 462520 screens richer than that median.

Fair Value models

Each model estimates fair value its own way; the Fair Value above is the evidence-weighted blend. Evidence (0–100) measures how completely this model’s inputs are available: well-fed models carry more weight in the blend. The spread across models is intentional, each one stresses a different value driver; dividend models, for instance, come out structurally low when payout is small.

Widest divergence: Asset-Based (12,520 KRW) versus Multiples (3,752 KRW). Highest evidence: Residual Income (76).

Frequently asked questions

How we calculate Fair Value

Each company is valued through a stack of independent intrinsic-value models (DCF variants, residual-income, multiples and more), blended into one family-balanced consensus and weighted by how much trustworthy data backs it. A separate quality layer scores the fundamentals. Every input is real reported data, nothing guessed.
